"Since the control system and positioning are decentralized in the drives of drive-based applications, the complete calculation and execution of the movement also take place there," explains Heiko Berner, System Support Coordinator at STOBER. "The nominal values for position and speed must be converted into movements accurately and precisely."
However, application classes AC1 and AC3 reach their limits when it is necessary to transmit nominal values for multiple axes synchronously, for example, in servo drives for machine tools and robots.
To carry out these complex motion control tasks, the drive specialist now supports application class AC4. This is suitable for control-based positioning with synchronized cyclic specification of the nominal value for motion control drives with advanced central intelligence and the patented "Dynamic Servo Control" position control concept.
“We can seamlessly integrate our drives into Siemens’ motion control system,” explains expert Berner. Mechanical components, such as speed and positioning axes, measuring probes, cams, and cam discs, as well as cyclic communication, are mapped and translated to suit the drive. STOBER has equipped its SC6 and SI6 series drive controllers for seamless integration with Siemens control systems. They are networked via PROFINET RT (Real-Time – AC1, AC3) or PROFINET IRT (Isochronous Real-Time – AC4). Users simply need to integrate the drive controllers into the Siemens TIA portal within the Siemens environment using the standardized interfaces.
"STOBER drive controllers can also be simulated without the need to use the corresponding hardware," explains Berner.
